Curl POST提交出现404

使用curl 访问基于Authorization Basic认证页面,这是成功的代码

function postJsonData($json){
    $ch = curl_init("http://localhost/issues.json");
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");

// Headers

    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        "Authorization: Basic base64($username.$password)",
        "Content-Type: application/json",
    ));
//$filename = "test.json";  /// Change this path to yours
//$fd = fopen($filename, 'r');
//curl_setopt($ch, CURLOPT_UPLOAD, TRUE);
//curl_setopt($ch, CURLOPT_INFILE, $fd);
//curl_setopt($ch, CURLOPT_INFILESIZE, filesize($filename));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json); // POST this data

// Send synchronously

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    $result = curl_exec($ch);
    curl_close($ch);
    return $result;
}

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); 修改成 curl_setopt($curl, CURLOPT_POST, true); 之后提交httpstatus 404,不知道为什么，记录一下
